Wingless type protein (Wnt protein) is a group of protein which plays an important role in the process of animal growth and hemopoiesis,the signaling pathway they conducted was called Wnt signaling pathway,and its abnormal activation can lead to many tumors,include lung caner.As a tumor suppressor gene,WIF-1 can restrain the activation of Wnt signaling pathway,which can avoid lung cancer.WIF-l's methylation can downregulate the expression of WIF-1,which can activate Wnt signaling pathway and cause lung cancer.So the detection of WIF-1's methylation may contribute to clinical diagnose of lung cancer,and therapy of WIF-1 's methylation may be one of the treatment metheds of lung cancer.

In order to assess colonic motility of chronic constipation, colonic transit test was carried out in 34 patients with chronic constipation and in 20 healthy subjects. 20 radiopaque markers are ingested at 8 am before the day test, and plain abdominal films were obtained at 24 h, 48 h and 72 h. The normal value of colonic transit test was 16(80%), or more markers passed after 72 h. By means of transit time study, 34 constipated patients were classified into 2 groups: 12 normal transit patients and 22 slow transit patients. There was no difference in colonic transit time between normal transit patients and controls (P＞0.05). Patients with slow transit had more markers left in right colon, left colon and rectosigmoid colon at 48 h (P＜0.01, respectively) and 72 h (P＜0.01, respectively). According to the transit index, 22 slow transit patients were divided into 3 types: 10 cases colonic stasis, 8 cases outlet obstruction and 4 cases colorectal stasis. The study suggests that chronic constipated patients have abnormalbilities of colonic transit.

Objective To explore the feasibility and effect of intervention therapy for patients subclavian steal syndrome.MethodsThe data of 35 patients with subclavian artery steal syndrome in neurology department of our hospital from October 2014 to March 2016 were retrospectively analyzed.All patients treated with pecutaneous transtuminl angioplasty and stenting.The degree of vascular stenosis was measured by digital subtraction angiography, the inter-arm blood pressure was tested by mercury sphygmomanometer.And the clinical manifestations before and after surgery were compared.All patients were followed up for 1 to 12 months,the clinical manifestations,blood flow and vascular stenosis degree in patients were observed.Results All patients were finished pecutaneous transtuminl angioplasty and stenting successfully,7 patients with serious vascular stenosis treated with percutaneous intravascular balloon dilatation at first.The average artery stenosis before operation was(74.73±10.42)%,while it decreased to(8.60+3.16)% after surgery,which were measured by DSA,the difference was significant(P<0.01).The result from mercury sphygmomanometer showed that the inter-arm blood pressure from preoperative(44.43±10.12)mmHg to postoperative (10.09+4.80)mmHg (2~7 days),systolic blood pressure differential minified significantly,the difference was significant(P<0.01).All patients were followed up for 1 to 12 months,support forms of 34 cases were in good conditions without new narrow,1 case appeared narrow in postoperative 7 months,then recovered after reoperation;symptoms of 28 cases significantly improved or disappeared,5 cases partly alleviated,2 cases had recurrence,no serious complications such as thrombosis and severe infarction occurred.Conclusion The pecutaneous transtuminl angioplasty and stenting is stable,high successful and low short-term recurrence rate for subclavian steal syndrome,which is good to alleviate vascular stenosis,reduce interrm blood pressure difference and improve clinical manifestation.

ObjectiveTo study the occurrence and influence factors of drug-induced injuries of vital organs caused by traditional Chinese medicine injection.MethodsChina Hospital Knowledge Database (CHKD) from 1993-2013 and case reports concerning adverse effects and drug-induced diseases caused by traditional Chinese medicine injection from Wanfang Data Knowledge Service Platformwere retrieved. Indicator systemwasestablished and relevant contentsweresummarized and analyzed.Results34 types of traditional Chinese medicine injectionswereincluded and 699 drug-induced diseasesweresummarized, taking up 53.98% of the total adverse effects. Among them, the top three included in the drug-induced diseaseswere acanthopanax injection, safflower injection and Mailuoning injection.

Objective To investigate the effect of Ginkgo biloba extract on serum divalent metal transporter1 ( DMT1 ) , glucose regulated protein 75(grp75) and nerve function in patients with Parkinson disease.Methods 38 cases of patients loith parkinson disease according to different drugs were divided into experimental group and control group, 19 cases in each group.Control group was treated with levodopa and Benserazide tablet, experimental group on the basis of control group, was given Ginkgo biloba extract tablets, treatment for 4 weeks.After treatment, DMT1, grp75 and cognitive function of all patients in substantia nigra were detected.ResuIts Compared with before treatment, two groups of patients with lower DMT1 level (P<0.05), compared with control group, experimental group of patients with lower DMT1 levels (P<0.05).Compared with pre-treatment, two groups of patients grp75 level was higher (P<0.05), compared with control group, experimental group after treatment grp75 level was higher (P<0.05).Compared with before treatment, the two groups of patients with MoCA scores were higher (P<0.05), HAMD scores were lower (P<0.05).Compared with control group, experimental group after treatment MoCA scores were higher (P<0.05), HAMD scores were lower (P<0.05).ConcIusion Ginkgo biloba extract can significantly reduce the level of DMT1 in the substantia nigra of Parkinson patients, increase the level of grp75, and improve the cognitive function.

Objective To investigate the trends in and characteristics of syphilis epidemiology in China,and to provide a scientific basis for the development of control strategies.Methods An epidemiological study was performed on syphilis cases reported from 31 provinces,autonomous regions and municipalities between 2000 and 2013.Results The reported syphilis incidence increased yearly from 6.43 per 100 000 person-years in 2000 to 32.86 per 100 000 person-years in 2013,with an average annual growth rate of 13.37％.Syphilis was reported in most (99％) counties/districts in China mainland except for a few remote mountain areas,with a significant difference in the incidence of syphilis between different regions.The regions with a high incidence of syphilis included minority areas in Northwest China (Xinjiang,Qinghai and Ningxia),Minjiang River area,Yangtze River Delta (Zhejiang,Shanghai),Zhujiang River Delta (Guangxi,Guangdong),etc.There had been a rapid increase in the incidence of syphilis in some regions previously reported to have a low incidence (such as Guizhou,Shaanxi,Henan,etc).Among the reported cases,female patients predominated with an average male/female ratio of 0.92 ∶ 1.The incidence of syphilis was highest in the age group of 20-39 years,but increased yearly by more than 30％ in the population aged ＞ 60 years.Of 20 occupations,peasant workers accounted for the highest proportion (31.56％) of syphilis cases,and retired population showed the most rapid increase by about 27.35％ per year.The constituent ratio of primary and secondary syphilis in all the syphilis cases had declined yearly,while that of latent syphilis increased by more than 50％ after 2010.Conclusions Syphilis remains a major public health issue in China,and measures based on the epidemiological features are urgently needed to effectively control epidemic syphilis.

During growth and progression, the microenvironment of tumors suffers a series of abnormal characteristics, which include hypoxia, acid pH, increased oxidative stress, excess glutathione (GSH), as well as certain overexpressed enzymes. Although affect or limit the cancer therapeutic outcomes, these factors provide possible approaches to strategies for cancer detection and novel therapy at the same time. Recently, based on these properties of the tumor microenvironment (TME), various kinds of responsive nano-platforms have been continuously developed and applied in cancer theranostics preliminarily. Thus, this review would introduce the typical features of TME firstly, then detailly summarize the design principles and research progress of corresponding hypoxia-responsive, pH-responsive, redox-responsive, enzyme-responsive, dual-responsive and multi-responsive nano-platforms. Finally, the challenges and the perspectives of the TME-responsive nano-platforms are briefly discussed.

The endothelial-to-mesenchymal transition (EndMT) in endothelial cells contributes to the development of cardiac fibrosis,ultimately leading to cardiac remodeling.In this study,the effects and molecular mechanisms of celastrol (CEL) on transforming growth factor-β1 (TGF-β1)-induced EndMT in human umbilical vein endothelial (HUVEC-12) cells were investigated.The presented data demonstrated.that CEL significantly blocked the morphology change of HUVEC-12 cells induced by TGF-β1 without cell cytotoxicity.In accordance with these findings,CEL blocked TGF-β1-induced EndMT as evidenced by the inhibition of the mesenchymal markers,including collagen Ⅰ,Ⅲ,α-SMA,fibronectin mRNA expression,and the increase in the mRNA expression of endothelial cell marker CD31.These changes were also confirmed by double immunofluorescence staining of CD31 and vimentin.The in vitro scratch assay showed that CEL inhibited the migration capacity of the transitioned endothelial cells induced by TGF-β1.Further experiments showed that the beneficial effect of CEL on blocking the EndMT in HUVEC-12 cells was associated with the suppression of the TGF-β1/Smads signalling pathway,which was also confirmed by the inhibition of its downstream transcription factor snail1,twistl,twist2,ZEB1 and ZEB2.These results indicate that CEL blocks TGF-β1-induced EndMT through TGF-β1/Smads signalling pathway and suggest that it may be a feasible therapy for cardiac fibrosis diseases.
